CULTIVATOR.

Application led August 30, 1926. Serial No. 132,555.

said fenders may be varied as desired and in accordance with `the crop cultivated, or the tenders vmay be raised to inoperative position by said means, and said means can be actuated with very little ell'ort on the part ot' the operator.

A i'urther object is to provide an attachment for cultivators and the like which can be associated with any type cultivator with none or slight change thereto, and said attachment can be operated from the seat or the cultivator to adequately and expeditiously adjust the fenders of said cultivator at any desired height.

Another object of the invention is to provide an attachment tor adjusting tenders of cultivators, that is strong and durable, easy to attach to the cultivator, simple to operate, and can be operated in unison with the control lever for the cultivator blades.

This invent-ion also consists in certain other features or' construction and in the combination and arrangement ot the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reterence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a top plan view ot a cultivator with the attachment which terms the subject matter of the present invention applied thereto.

Figure 2 is a sectional View taken vertically through the cult-ivator.

Figure 3 is an edge elevation of the control lever for lthe 'attachment and showing the same secured to the control lever for the blades ot' the cultivator.

Figure 4 is a front view of Figure 3.

Figure 5 is a sectional view taken on line 5--5 of Figure 3.

Figure 6 is an edge elevation ot the supporting arm which forms a part of the invention.

Figure 7 is a top plan view of the supporting arm.

Referring to the drawings in detail the letter A indicates the main cross frame of the cultivator as shown, and B the hand lever for rotating the cross frame, tor raising and lowering the cultivator disks and blades. The tender C is or' the usual cross-sectional iii-shape construction and has secured thereto one ot the ends of connecting bars E,

while the opposite ends ot said bars are pivotally associated with the tongue F of the cultivator.

The attachment which forms the subject matter of the present invention is shown applied to the cultivator in Figures 1 and 2- and includes a supporting arm l formed trom a pair ot superposed elongated strips with one of their ends thereof arranged in substantially V-shaped conh'guration as at 2, and a similar shaped plate 3 is secured in opposed relation thereto so as to provide a clamp for fixing the supporting arm to the main cross trame as clearly shown in Figure 2 ot the drawings. The strips are bent downwardly and rearwardly trom their secured ends and thence incline upwardly to terminate in spaced relation to provide apertured ears 4 and 5 between which is journaled a grooved pulley 6 having its journal pin 7 secured in the apertures of the ears by a nut as clearly shown in Figures 6 and 7 ot' the drawings. A substantially U-shaped guard 8 is secured to the ends of the pin 7 and overlie the pulley 6 as best shown in Figure 6.

The means for raising and loweringthe tender C includes a chain 9 which has one end secured to the fender and is thence passed over the grooved pulley 6, while its opposite end is secured to the control lever 10 which is associated with the hand lever B by an adjusting means which includes a disk member 11 formed with spaced lugs 12 arranged upon opposite sides ot the lever B, and an opening is centrally arranged in the disk member 11 for receiving a bolt 13 which passes through said lever B and also a disk member 14 having an ear 15 formed thereon for securing said disk member 14 to the lever 10 as suggested in Figures 1 and 3 of the drawings. The disk member 14 is also provided with a slot to accommodate the lever 10. The confronting faces ot the said disk members 11 and 14 are formed with cooperating teeth and a coil spring 16 surrounds the bolt 13 with its end convolutions engaging a washer 17 and disk meinber 14 respectively, to hold the teeth of the disk members in cooperating engagement as `will he i'eudilv uppzn'ent. ill. nut 1S is; thence cxl'eni'ling i'i'iui'wanifllv thei'elixoin, n
